PRINTING-PRESS CHASE.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed October 14, 1919. Serial No. 330,628.

To all whom it may concern:

Be it known that I, CLARENCE H. WEANT, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improyements in Printing-Press Chases, of which the following is a specification.

This invention relates to improvements in printing press chases and has for its ob ect to provide a chase so constructed and arranged that smaller chases may be used 111- side thereof.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification and pointed out in detail in the appended claims. A in the accompanying drawing- Figure l is a front elevation of my invention showing a small chase within the large or master chase.

Fig. 2 is a vertical section of Fig. 1 on the line 22.

Fig. 3 is a vertical section of the large chase on the line 3-3 of Fig. 1.

Referring to the accompanying drawlng forming part of this specification and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the large or master chase and 2 the small chase. The large chase l is fitted within the bed of the press 3 and is held in position by the clamp 4. The small chase 2 fits within the large chase 1 and rests on the beveled edge 5 on the inner surface of the ear 6, the ends of the chase 2 impinging against the shoulders 7. The chase 2 is locked in position by the pins 8 which project through the large chase 1 and have their lower beveled edges impinging against the upper beveled edge of the chase 2. The said pins 8 project from the lower surface of the piece 9, which latter fits within a cut out 10 in the top of the chase l. The said pins are held normally out of engagement by a coil spring 11 in the upper edge of the chase 1, the said pins being held against said chase by the action of the clamp 4 on the bed 3 of the press. The lower end of the chase 1 is provided with a lock 12 pivoted in said lower end of the chase 1 and having a beveled upper surface which impinges against the lower beveled surface of the chase 2. The lower end of said lock proects under the lower surface of the bed 3 thus preventing the chase 1 from working upwardly on account of any pressure against the chase 2. lVhen the chase 2 is lifted from the chase 1 the spring 13 forces the lower end of the lock 12 from under the bed 3 and permits the chase 1 to be lifted from the press.

It will thus be seen from my present invention that it will not be necessary to rely on the special chase made for the press but a smaller chase may be employed if necessary when the larger pieces are in use.

Having thus described my invention what I claim is.

1. The combination of a printing press chase having ears on the inner edge thereof provided with recesses, a smaller chase adapted to fit within the said first named chase and resting in said recesses, two pins projecting through the first named chase and having beveled lower edges adapted to impinge against the beveled edge of the smaller chase and lock it in the first named chase, and a spring to release said pins when the first named chase is removed.

2. The combination with a printing press, of a chase adapted to fit the bed of said press, a lock on the lower end of said chase having a beveled upper surface impinged against the lower beveled surface of the smaller chase, a small chase set within said first named chase, a lock on the upper edge of said first named chase adapted to lock the small chase therein.

3. The combination with a printing press of a large chase having a cut-out in its upper edge, a plate fitting within said cut-out and having two pins projecting therefrom and extending through the said large chase and having beveled lower ends, a spring to hold said pin normally out of engagement with the smaller chase, and a small chase adapted to fit within the large chase and held therein by said pins.

In testimony whereof I aflix my signature.

CLARENCE H. WEANT.
